Description

technical field

[0001] The invention belongs to the technical field of auto parts, and in particular relates to an auto interior trim and a molding process thereof. Background technique

[0002] With the development of the automobile industry, the NVH performance of the whole vehicle is getting more and more attention, and the requirements for the NVH performance of auto parts are also getting higher and higher. The car roof is an important sound-absorbing part, which plays a major role in the whole vehicle; there are two main molding processes for the car roof molding process, one is the dry molding process, also known as the hot material cold molding method, the molding method is mainly The PU composite board is heated, and the temperature of the board is about 180°C, and the product fabric is molded in the mold;

[0003] The second is the wet forming process. The wet forming process is divided into a wet one-step forming process and a wet two-step forming process. The we...
